In Germany February 14,1981 7 a 11 Claims. (01. nit-121) This inventionrelates to combined typewriting and calculating machines.

In combined typewriting and calculating machines as hitherto known, itis only possible to add up the amounts which succeed one another inhorizontal series in the column totalizers which are arranged on thepaper carriage, and to calculate the sum and diflerence of these amountsin the cross totalizers.

In the case when definite forms have to be completed, it is, however,desirable-to add the amounts which succeed one another in verticalseries in the column totalizers and also, of course,

to calculate the sum and difference of these amounts in the crosstotalizers.

According to the invention, the above method of calculation is renderedpossible by means of a totalizer carriage which is controlled by theusual escapement and a paper carriage displaceable independently of thetotalizer carriage.

The accompanying drawings illustrate, by way of example, one form ofconstruction of the invention.

A description of the known Mercedes "Addelektra combined typewriting andcalculating machine to which the invention has been applied, by way ofexample, is as follows:-

The machine frame I, Figure 3, supports, by 10 1 means of the rails, 2and 2, a carriage frame .4

which has a length, for example, of cm. In this carriage, however, noplaten is arranged. The purpose of this arrangementiwill be explainedhereinafter in a detailed manner. On 15 the right-hand side of thecarriage frame, 4, the carriage release lever, B, is mounted on a screw,5, Figures 2 and 5, so that it can swing in a downward direction, and onits extension, 6a, one end of the carriage release rail, 1, Figure 3, is20 secured. The rail, I, at its other end, is rigidly attached to alever, 8, which is arranged on the left-hand side of the carriage frame,4, and which is mounted on a screw, 9, so that it can pivot If thecarriage release lever is de- 25 pressed, then the carriage releaserail, 1, acts, by way of the parts, III to I5, upon the loose tooth ofthe usual typewriter escapement and withdraws it, whereupon the carriageframe, 4, may be freely moved to the right or to the left. For thepurpose of returning the carriage frame, 4, into position, a rack, I6,is secured to it, Figures -1 and 3.. The rack, I6, is in mesh with agear wheel, II, which is secured to the axle I8, by a pin.v The axle, I8, is mounted in a 35 small fixed pedestal bearing, I8,-and on its end.remote from the gear wheel, II, it supports a bevel wheel, 20. with thebevel wheel, 20, a bevel wheel, 2|, Figure 1, engages, the latter 1wheel being secured to an axle, 22. The axle, 40

' actuates the type levers. On the shaft portion,

29, a second coupling member ill, is also mounted which incontradistinction to the coupling memher, 2!, is so arranged withrespect to the shaft 55 portion, 29, that it cannot rotate thereon, butcan be displacedinan. axial direction. On the free end of the shaftportion, 29, is arranged a further coupling member, 3|, which, ifrequired, may be coupled with a corresponding coupling member, 32, bydisplacing the shaft,'33, which carries thecoupling member, 32, by meansof a knob, 34, from its position as shown in Figure 1, towards the left.The shaft, 33, is adapted to be rotated inthe direction e by means of achain wheel, 35, which is keyed to it, and the chain, 35a, Figure 3,driven by-the motor, M;

The return movement of the carriage is effected, provided that thecoupling members, 3| and 32, are engaged, in a known manner, thecoupling member, 30, being engaged with the coupling member, 28, by alever, 36, which is actuated by the right-hand margin setter, Rr,through suitable mechanism which is not shown in the drawings, and thiscauses, by means of the already 'mentioned gear wheels, H to 21, thereturn movement of the carriage to the right. The disengagement of thecoupling members, 23 and 30, is effected by the left-hand margin.setter, Rx, when the carriage frame 4, arrives at its extremeright-hand position. The line spacing of the platen is, in the presentcase, not effected in the usual manner, in dependence upon the carriagereturn mechanism, but in dependence upon the carriage movement in amanner which will be hereinafter described.

In the two side walls, 3? and 38, Figure 1, of the frame, 8, bearingsare arranged in which the driving shaft, 39, Figure 3, for driving thedifierential members, is mounted. The shaft, 39, is driven by a chain,35a, from the motor, M, in the direction of the arrow, 0. The ratchetwheel, 46, is arranged on the shaft, 39, and participates in itsmovement. A similar ratchet wheel, it, is provided for each of the tencalculating keys, M. The calculating key levers, d2, are mounted on themachine frame, l, in

such a manner, that they can pivot around the shaft, 53, and are held inthe position shown in Figure 3, by the springs, 35, which are attachedat one end to the hooks, 44, of the calculating key levers, and, at theother end, to the fixed hooks, Q5, this position being determined by thecontact of the noses, ll, on the calculating key levers with the stopbar, dd.

If a key, ii, is depressed, then the key lever, 52, pivots around theshaft, 33, in a clockwise direction, and its arm, Q3, which extends in arearward direction, releases the pawl, 50, which is slidably mounted onthe cam, 5|, the latter being mounted on the shaft, 35, in such a mannerthat it can rotate freely thereon. In consequence of this the pawl, 50,under the action of the compression spring, 52, which acts upon it,moves in the direction of the arrow, (2, and its nose, 53, engages withthe continuously rotating ratchet wheel, Gil. This engagement causes thecam, 51!, which corresponds to the depressed key, M, to be coupled tothe,ratchet wheel, fill, and therefore with the shaft, 39, for onerevolution only.

The swinging movement of the lever, 42, also causes a member, 55, whichis slidably mounted on the lever by means of the pin -and-slotconnections, d3, Mia and 33?) and 2330, to be moved towards the left sothat the hook, 56, engages under the stop bar, 58, by the action of thespring, 55, which at one end is connected to the member, 54, and at theother end to the arm 43 of the lever, 42. The nose, 51, of the member,54-, is thereby caused to move into the path of the nose, 58, of thepawl, 50, which in the meantime has been released and has moved past thearm, 43, and the nose, 51, in the direction of the arrow, c, and the keylever, 42, is locked in its depressed position by the nose, 55, of themember, 54. The revolution of the cam, 5|, causes the differentialmember, 60, the roller, 59, of which contacts with the cam, to move in adownward direction under the action of the spring, 60a, and thereafterto be moved upwards by the rotating cam, 5|. The movement of thedifferential member, 60, causes a slot, 8|, therein, which slot isshaped to correspond to the value of the particular key, 4|, depressed,to act upon a shaft, 62, of an oscillatable frame fixed to the rotatablymounted shaft, 63, and consisting of a number of plates, 64, fixed onthe shaft, 63, the above mentioned shaft, 62, and another shaft, 65,which acts as a stiffening stay. The oscillation of the frame, 52, to55, causes a swinging movement of a one-way toothed segment, 66, fixedto the shaft, 63, and this movement of the toothed segment causes,through a reversing gear which is not shown in the drawings and whichcan be adjusted by means of the knob, 6611, Figure 1,

the main driving wheel, H, of the column totalizers to be rotated eitherin an additive or subtractive sense, according to the position in whichthe knob, 55a, has been set. If one of the columntotalizers, 51 to 9|a,which are attached to the supporting rail, T, of the carriage, 4, is inthe operative position, the main driving wheel, H, then transmits theamount by way of the corresponding driving wheel,'H|', and the wheel,E2,

of the corresponding column totalizer to the wheel, H3, of the numberwheels, Z, whereby the latter are positioned to correspond to the amountintroduced.

After the cam, 5!, has made a complete revolution, the nose, 5 ,of thepawl, 55, abuts against the nose, 51, of the member, 54, whereby thecam, 5|, is disengaged from the ratchet wheel, 50. The contactgg f thepawl, 50, with the nose,

51, of the member, 54, causes the latter also to move against'the/action of the spring, 55, into the position shown in Figure 3,which returns the key lever, 42, into its rest position and realong withit which under the action of its spring 93 is normally held against thestop bar 94. If, therefore, the differential member 60 moves downwards,the corresponding numeral writing key lever 95 swings around its pivot95 against the action of its spring 93. The pawl, 98, which is mountedon a pin, 91, on the key lever, 95, causes the coupling hook, 99, toengage with thetoothed shaft, N, which rotates continuously in thedirection of'the arrow, e, so that the coupling hook is moved by thetoothed shaft towards the and consequently also the paper carriage, I99,

which moves in the latter, and will be hereinafter described, are movedone step towards the left by means of the usual spring drum.

In the front of the machine frame, I, the totalizers are mounted, and onits front wall, I06, Figures 1 and 3, is arranged a bracket, I 01, whichsupports two cross totalizers, I08 and I09, which are movable togetherin a lateral direction. With each ofthe cross totalizers, I08 and I09,is connected a set of links for the clear sign impression device whichin the following is shortly described for the purpose of a betterunderstanding of the invention itself.

On a shaft, IIO, Figures 1, 3 and 4, which rests in supports on themachine frame, a two-armed lever, consisting of the bridge member, IIIand arms, I I2 and I I3, isrotatably mounted and is acted upon by aspring, H4, in the anticlockwise direction around the shaft, IIO. A pin,which is riveted to the arm, II3, Figure 4, ro jects into the slots,II6, of two levers, H1 and H8. The levers, H1 and H8, are provided withhooks, H9 and I20, which act in conjunction with the projections, I 2|,arranged on the column totalizers, H, 13, 11, 18, 19, 8|, 82, 84, 88 and9Ia. The projections, I2I, of the column totalizers, H, 18, 8|, 84 and9Ia, act upon the hook, I20, of the lever, H8, and the projections, I2I,of the column totalizers, 13, 11, 19, 82 and 88, act upon the hook, II9,of the lever, H1. The levers, Ill and H8, are provided with triangularopenings, I22, into which projects a pin, I23, which is fixed to themachine frame. The

levers, H1 and H8, are pivotably interconnected with the levers, I24 andI25, which are arranged on the machine frame in such a manner as to becapable of pivoting on the screws, I26 and I21. The levers, I24 and I25,are acted upon by the tension springs, I28 and I29, in a clockwisedirection. The levers, I24 and' [25, co-act with the levers, I30 andI3I, which are arranged on the shaft, I32, so that they can pivot freelythereon, the latter shaft, I32, being arranged under the bracket, I01,Figure 3.

The lever, I30, is connected at its forwardly directed end, Figure 4, bymeans of a U-shaped rail, I33 with the similarly disposed end of alever, I34, which is rotatably mounted on the shaft, I32, and the lever,I3I, is similarly .con nected by means of a U-shaped rail, I35, with thelever, I36, which is rotatably mounted on the shaft, I32. I

The U-shaped rails, I33 and I35 are slidably connected by means of therollers, I31 and I38, with displaceable sliding members, I39 and I40,which can move vertically on the front of the cross totalizers, I08 andI09. Each of the slides,

I39 and I40 has two arms, MI and I42, which with the number wheeldriving wheels, I49, I49a,-

Figure 3, which in a known manner, have a shortened tooth in theposition which corresponds to the zero position of the number wheels,

B, Ba.

On the shaft, I32, Figure 4, a two-armed lever consisting of a bridgemember, I50'and arms, I5I and I52, is rotatably mounted. The arm," I5I,is provided with a knob, I53. To the arm, I52, Figure 3, which extendsdownwards, a lever, I55, is connected by means of a screw, I54, thelever at its free end being provided with a curved slot, I56. To thearm, I52, is pivotably connected, by means of a screw, I51, a link, I58,the

free end of which is fork-shaped and embraces in a known manner a pin onthe intermediate lever co-acting with the type lever which carries the"clear sign type. The key lever, I59, Figure 1, by means of'which theclear sign type lever is struck, is not provided with a key,'but isconnected with the lever, I55, by means of a pin, I60, Figure 3, whichprojects into the slot, I56, on the lever, I55. Further, the key lever,I59, acts also upon the clear sign type lever through parts which aresimiliar to those described by the references-91 to I00. I

The column totalizers, 61 to 9Ia, are provided with; engaging members,I6I, Figure 3, which project into the path of a coupling mem berconnected by means of a screw, I62, Figure l, with the left-hand crosstotalizer, I 08. At the other end the coupling member which in the mainconsists of the link, I63, engages, by means of a pin, I64, in'ahorizontal slot, not shown, in the front wall, I06, of the calculatingmechanism. The coupling member has further a hook, I65. which ispivotably connected, by means of a pin, I66, with the rod, I63, and ismaintained in its operative position by means of a spring which is notshown in the drawings. A second hook, I61, serves, as is known,..-forthe purpose of preventing the mechanism over-shooting its position onthe return movement. The cross totalizers, I08 and I09, as well as thecoupling link, I63, are maintained in their normal posi tion asillustrated in Figure 1, by a spring which is not shown in the drawings.The coupling links, as is known, have the function of carrying the crosstotalizers, I08 and I09, along with each column totalizer to the left,until the amount to be registered in the lowest denominational positionhas been registered, whereupon the cross totalizers are automaticallydisengaged from the column totalizers and spring back to the right underthe action of their springs, after which they are carried along to theleft by the next column totalizer.

The clearsign impression device is disengaged by the carriage releaselever. 6, through the parts 1, I0, II and I68.to I10, Figures 3 and 4.When the carriage release lever, 6, is depressed it swings around thescrew 5 (Fig. 5) in the anticlockwise direction. Inasmuch as theangle-shaped bar 1 (Figs. 5 and 3) is fixed to the carriage releaselever 6 and to the lever 8 (Fig. 3), the parts 618 are swinging togetheras a whole around the aligned pivots 5 (Fig. 5) and 9 (Fig. 3) of thelevers 6 and 8 in the clockwise direction with regard to Fig. 3.Consequently, the angle-shaped bar 1 acts upon the roller I of the leverI2. Owing to the fact that the lever I2 and the lever I68 are in rigidconnection with the shaft II, the parts I0, I2, II and I18 are rocked inanti-clockwise direction and, the rod, I69, moves in the direction ofthe arrow ,1; and thereby operates, by means of the member, I 69a. thecranked lever, I 10, Figure 4,

.in a clockwise direction, whereby the latter with its forwardlydirected arm, moves the two-armed lever, II2, III, II3, around theshaft, H8, in a clockwise direction. This movement causes the pin, II5,to move the levers, H1 and H8, in a downward direction and brings thehooks, II9 and I28, which are on the latter, out of the path of theprojections, I2I, of the column totalizers, II, 13, 11, 18, 19, 8|, 82,84, 88 and 9Ia. It is impossible, therefore, for the clear signimpression devices to be actuated during the displacement of thecarriage, 4, by release lever, 6. I By means of the two settingplates,I880. and l89a, Figure 3, the cross totalizers, I88 and I89, areadjusted for addition, subtraction or are disengaged. The setting plate,I68a, serves to control the type of calculation in the cross totalizer,I89, and the setting plate, I69a. serves tocontrol the type ofcalculation in the cross totalizer, I88. The setting plate, IBM, isadjusted by the knob, H821, and the 'setting plate, 5911., is adjustedby the knob, I1I, in the manner described in U. S. Patent 1,349,024. Inthis patent, the setting plates are shown in Figures 7 to 13 anddesignated by reference numerals-45 and 46. The setting plates, I68a andHim, are adapted to actuate the cranked levers, I12 and I13, Figure 7,which are pivotably mounted on the pins, I14 and I15, on the front wallof the calculating mechanism. The levers, I12 and I13, are acted upon bythe spring, I16, in such a manner that they abut against the stop pins,I11 and I18, which are arranged in themachine frame, and this determinestheir normal position. The cranked lever, I12, is pivotably connected bymeans of a connecting rod, I19, with a lever, I8 I, which is pivotablymounted on the shaft, 188. A pin, which is arranged on the lever, I8I,and which is not shown in the drawings engages in an annular groove in agear wheel, not shown, and which is driven through intermediate gearingby the toothed segment, 68, the above mentioned gear wheel beingnormally in mesh with the gear wheel, I82, which is secured to a hollowshaft, I83. On the right-hand end of the hollow shaft, I83, is secured agear wheel, I84, which meshes correspondingly to the decimal positions,with the transmissiongears of the left-hand cross totalizer, I88, assoon as the latter is carried along by a column totalizer, On the leftof the gear wheel, I82, a second gear wheel, I85, is secured to thehollow shaft, I83, and is constantly in mesh with an intermediate gearwheel, I 81, which is rotatably mounted on a pin. If the gear wheel,which is not shown on the drawings, is in mesh with the gear wheel, I82,then the number wheels of the cross totalizer, I88, which are not shownin the drawings are operated in an additive sense. If on the contrary,the said gear wheel lies between the gear wheel, I82, and the gearwheel, I81, then the cross totalizer, I88, is not operated at all. If,finally, the said gear wheel is -meshed with the intermediate gearwheel, I81, then the cross totalizer, I88, is actuated in a subtractivesense.

The setting plate, IEBa, operates in conjunction with the cranked lever,I13. The lever, I13, is pivotally connected with a lever, I89, by meansof a connecting rod, I88. On the free end of the lever, I89, is arrangeda pin, which is not shown in the drawings, and which engages with anannular groove on a gear wheel which also is not shown on the drawingsand which is actuated by the toothed segment, 88. On a shaft, I98, agear wheel, I9I, and a gear wheel, I92, are areans of the carriageranged. If thegear wheel which straighter-a 1 above mentioned gear wheellies between. the two gear wheels, I9I and I92, then the number wheelsof the cross totalizer, I89, are not actuated at all. If, however, thesaid gear wheel is meshed with the intermediate wheel, I94, which isloosely arranged on the pin,- I88, then the number wheels of the crosstotalizer, I89, are actuated in the subtractive sense through the gearwheels, I92 and I93.

On the 'forward longitudinal member, I95, Figure 2, of the carriage, 4,a rail, I91, Figures 2 and 8, is secured by means of the screws, I96. Onthe rail,. I91, a roller, 288, runs,-Figure 3, the roller being fixed inthe front member, I98, of the paper carriage, I99. The member, I98, isof U-shape and is fixed on the right-hand side by means of the screws,28 I Figures 2, 5, 6 and 8, to the right-hand part, I 9911, of thecarriage, I99, and on the left-hand side, 'by means of the screws, 282,Figures 2 and 3, to the left-hand part, I991), of this carriage. Bymeans of the paper guide plate, 283, Figures 1, 2, 3 and 5, and thesupporting rail, 284, Figures 3 and 5, the two side parts, I99a. andI995, of the carriage, I99, are rigidly connected to one another. On theright-hand side part, I99a, of the carriage, I99, a part, 286, issecured by means of the screws, 285, Figures 2, 5, 6 and 8. On the part,288, a lug, 281, is formed by bending over'to the right at a. rightangle, and on this lug, a roller 289, is rotatably mounted on a shaft,288. The roller, 289, runs on a rail, 2| I, of circular section fixed tothe rear longitudinal member, 2I8, of the carriage, 4, by means ofscrews which are not shown in the drawings.

On the lug, 281, of the part, 286, is fixed a part, 2I3, which isprovided with, an opening, 2I2, Figure 8. With this opening, a hook,2I5, provided with a loop, 2I4,is engaged, to which one end of adraw-band, 2I6, acting upon the carriage I99, continuously in thedirection of the arrow a, is attached. 'The spring casing, 2I 1, Figures2 and 5, to which the other end of the draw-band, 2I6, is secured, isarranged on the right-hand outer side of the carriage, 4. The drawband,2 I8, passes around a roller, 2I8, which is rotatably mounted on a part,2I9. The part, 2I9, in turn is secured to the carriage, 4, by means of ascrew, 228.

Through an opening, 22I, Figure 8., in the right-hand protecting cap,223, which is fastened by means of the screws, 222, to the right-handside part, I99a, of the carriage, I99, projects a lever, 224, whichraises the lower paper guide rollers, not shown, from the platen, I82.On the part, 288, Figure 8-, is a lug, 225, which is bent over to theleft and projects through the right-hand side part, 199a, of thecarriage, I99. On the lug, 225, a lever, 221, Figures 2 and 8, ispivoted by means of the screw, 226. A tooth, 228, formed on thelever'221, is adapted to act in conjunction with the teeth 229, of arack, 238, of angle section. A spring, 23I, Figures 6 and 8, which-atone end is attached to the arm, 232, of the lever, 221, and at its otherend which is fastened to a pin, 233, Figure 6, secured to the right-handside part, I990, of the carriage, I99, acts upon the lever, 221, in aclockwise direction around the screw, 226, so that 197 TYP the tooth,228, of this lever is always in engagement with one of the teeth, 229,of the rack, 239. The rack, 239, is provided with a number of screws,234, Figure 6, which project through elongated holes therein and are notshown in the drawings, so that the rack can be adjusted and locked inposition. A part, 236, is fixed to the lever, 221, Figure 8, by means ofthe screws, 235, the part, 236, acting in conjunction with anangleshaped rack, 236a, Figure 5, which is arranged on the fixed rearrail, 2. horizontal arm, the triangular teeth, 236b to 236e, Figure 2,which are disposed in the path of the part, 236, attached to the lever,221. If during the movement of the two carriages, 4 and I99, to theleft, the part, 236, contacts with one of the teeth, 236b to 236e, thenthe tooth, 228, of the lever, 221, is disengaged from the correspondingtooth of the rack, 239, and causes the paper carriage, 4, to spring tothe right as far as the next tooth of the rack, 239, under the action ofthe spring, 2".

In order to prevent the above springing movement taking place, which maybe desirable for reasons hereinafter described, the rack, 236a, isarranged so that it can be displaced vertically by screws, 236), Figure5, which project through long vertical slots in the vertical arm of therack, 236a. On the right-hand side part of the frame, a lever, 236k, ispivotably mounted on the screw, 2369', and this lever engages with itsreduced free end in a hole in the vertical arm of the rack, 236a. A rod,2361', at one of its ends is connected to the middle point of the lever,236h, and at its other end is pivotably connected to one end of thelever, 23610, which is pivotably mounted on the screw, 2361', on theright hand side part of the frame. On the other end-the forwardlydirected end-of the lever, 236k, there is arranged a spring pin, 236m,which may be engaged by hand with one of the two notches, 23611. (inFigure 5 this notch is covered by the spring pin, 236m) and 2360, in theright-hand side part of the frame. If the spring pin, 236m, is in thenotch 23611, then the teeth,- 2361) to 236e, of the rack, 236a, are inthe path of the part, 236, which is fixed to the lever, 221, Figure 8,and may, therefore, raise the tooth, 228, of the lever, 221, out of theteeth of the rack, 236a, and this enables the paper carriage, I99, toshift in jumps to the right.

If, however, the spring pin, 236m, is in the notch, 2360, then the rack,236a, is lowered through the levers, 2361c, 2361' and 236h, whereby itsteeth, 2362) to 236e, are moved out of the path of the part, 236,attached to the lever, 221, so that in this case, the two carriages, 4and I 99, can move uninterruptedly and together in uniform steps.

On the screw, 231, Figure 6, the release lever, 238, Figures 6 and 8, ispivotably mounted. On the arm,'239, of the lever, 238, a lug, 240, isformed by bending over at right angles and is adapted to act upon thearm, 232, of the lever, 221, whereby the tooth, 228, of the lever, 221,may be disengaged at any time from the teeth, 229, of the rack, 230, andthe paper carriage, I99, displaced independently of the carriage 4. Anangle piece, 242, which is secured by means of the screws, 24I, to thelug, 201, of the part, 206, Figure 8, projects with its part, 243, whichis bent over at a right angle, under the rail, 2I I, Figure 3, and thisprevents the carriage, I 99, from being lifted off.

On the part, I98, Figure 3, a U-shaped member, 244, is secured by meansof the screws, 245, and projects with its arm, 246, into an undercutpart,

The rack, 236a, has on its oearch 241, of the rail, I91, whereby thelifting-off of the carriage, I99, is also prevented at the front sideures 2, 3 and 9, a member, 249, is fixed to thecarriage side part, I99b,by means of the screws, 248. On the part, 250, of this member, whichpart is bent-over to the left at a right angle, a roller, 25I, isrotatably mounted and runs on the already mentioned rail, 2I I. To thepart, 259, is also fixed, by means of the'screws, 252, an angle piece,253, which with its part, 254, which is bentover at a right angle,projects under the rail, 2| I, and so prevents the carriage, I99, frombeing lifted off. On the extended part, 255, of the member, 249, atwo-armed lever, 251, is rotatably mounted by means of the screw, 256, adistance piece, 258, being interposed between the lever and the member,249. The end, 259, of the lever, 251, is bent-over at a right angle, aroller, 269, being rotatably mounted on the end, 259, and acting inconjunction with an angle piece, 262, fixed by means of the screws, 26I,to the rear frame.

On the arm, 263, of the lever, 251, a pawl, 265, is pivoted by means ofthe pin, 264, and the nose, 266, of this pawl is adapted to engage withthe teeth, 261, of the line space wheel, 268. A spring, 269, Figure 3,which engages at one end with the stem, 210, of the pawl, 265, and atits other end with a pin, 21I, riveted to the lever, 251, acts on thepawl, 265, in an anti-clockwise direction, Figure 3, so as to cause thenose, 266, to be held in engagement with the teeth, 261, of the linespace wheel, 268. A spring, 214, which at one of its ends is attached toa pin, 212 on the left-hand side part, I 99b, of the carriage I99, andat its other end engages with a pin, 213, of the lever, 251, acts uponthe lever, 251, in an anti-clockwise direction around the screw, 256.The rest or normal position of the lever, 251, and the pawl,

Room

265, is determined by a pin, 215, Figure 3, on the pawl contacting witha pin, 216, arranged on the left hand wall, I99b, of the carriage, I99,under the action of the springs, 269 and 214. The pawl, 265, extendsupwardly, Figures 3 and 9, through a slot, 265a, Figure 2, of the sheetmetal cover of the left-hand side part, I99b, and is provided with aknob, 265b, by means of which the pawl, 265, may be disengaged from theline space wheel, whereupon the platen, I02, may be freely rotated bymeans of the platen knob, I02a.

On the frame, I, a stop, 28I, is secured in position by means of thescrews, 280, Figure 5. If the carriage return key, AT, is depressed,then as is known, the carriage return coupling members, 28 and 36,Figure l, are engaged by means of levers which are not shown in thedrawings, and

in consequence, the carriage, 4, and with it, of

course, also the carriage, I99, move towards the right. During thismovement to the right, the tooth, 228, of the lever, 221, is raisedconsecutively, out of the zone of the teeth, 229, of the rack, by theaction of the teeth, 236a to 236b of the stationary bar 236a, upon thepart, 236, of the lever, 221, and this causes the paper carriage, I99,due to pull of spring 2I1, to move by jumps to the right in relation tothe carriage, 4, and this movement will continue until the tooth, 236b,which lies on the extreme right, has come into operation. The stop, 28I,prevents the paper carriage, I99, from moving further to the right. sothat from this point on, only the carriage, 4, can move to the rightuntil it is brought to a stop in a known manner by the opening of thecoupling members, 28 and 30, by the left-hand margin setter. During themovement of the carriage, I, to the right, in relation to the carriage,I99, the teeth, 229, of the rack, 230, of the carriage, 4, slide overthe cam, 228, of the lever, 221. The carriages, 4 and I99, are then inthe position as shown in Figure 2.

In the following, the working of the arrangement according to theinvention, is described, by way of example and by means of a tax returnschedule as shown in Figure 10.

This tax return schedule is subdivided by the perforations A to F, intosix parts which can be separated from one another. The part which issurrounded by the perforations, A, B and C, is the tax return proper.This contains the final calculation of the tax. On the right-hand edgeof this part, i. e., the part immediately on the left of theperforation, C, are the receipts for the quarterly tax payments whichmust be signed by the post oflice. 0n the left, next to the receipt forthe third quarter, is the receipt for the payment of the whole amount ofthe tax.

In the left-hand bottom corner of the schedule, the perforations, A andB, separate the payment voucher for the whole amount of the tax whichhas to be paid, and on the right-hand side of this are the postalsections which are destined for the taxation department.

This schedule is sent to the tax-payer already The income of thetax-payer is assumed to be... -3,900. BM. The State tax 48. RM. Freefrom taxation are 10. RM. Let the capital b 6 000 RM. The capital tax..-9 RM. The local rates 52.05 RM. The fire brigade tax 7. RM

19 to 9Ia, are blank. The totalizers which are.

A-addition; S=subtraction; D=disengaged. In order to perform thiscalculation, it is necessary in the first place to set the two cross andI69a, of the column totalizers, 61 to Na,

Figure 7, will be described before describing the manner in which theindividual column totalizers are forwarded to the operative position. 0!the column totalizers, 61 to 9Ia, which are arranged on the supportrail, T, the'totalizers, 61 to 19, are actual complete totalizers, whilethe totalizers,

blanks, and which as known consist only of totalizer casings and have nointerior mechanism such as gears, number wheels, etc;, serve merely foradjusting the cross totalizers, I08 and I09, to

the positions of Addition, Disengaged and Subtraction.

After all the column totalizers,- 61 to 9Ia, have been adjusted, and thetwo carriages, 4 and I99, have been moved into their position, as shownin Figure 2a, the address of the taxpayer is 'typed. As may be seen fromthat figure. by inans of the indexl, the two carriages are displacedsomewhat to the left, in which position the roller 260 of 'the leve r251 assumes the position according to line 1:,"which line with' regardttrFigure 10, corresponds to the left hand side otthe printing point onthe platen I02. As in the relative positions of the carriages I and I99according to Figure 2a, the tooth 228 of the lever 221 is in engagementwith the first teeth 229a of the rack 290 of the carriage 4, thecarriage I99 participates in the movement of the left of the carriage4.-

Although the same is true'with'regard to Figures 2 and 2b, reference maybe had, for the present, only to Figure 2a. Now, inasmuch as thecarriage I99 would jump to the right assoon as the part, 236, of thelever, 221, runs up on the tooth,

236D, and this action must, of necessity, be

prevented while the address is being typed or .for that matter, duringthe typing of any text.

The teeth, 23612 to 236e, are, insuch circumstances, renderedinoperative by positioning the spring pin, 236m, Figure 5, in the notch,2960,

and .thus these, teeth do not act upon the part, 236, of the lever, 221.Thereafter the name Herman Miiller is typed by striking the type keys,ST, Figure 2a.

After the name Hermann Miiller has been typed, the ,two carriages 4 andI99 have moved so far to the left that the roller 260 of. the lever 251,assumes the position according to line a Nmnber k Betting SettingReading mg 2,: 0 misc cross cross.

In thisposition, as may be clearly seen from Fig.2b, the roller 260 lies stillon the horizontal edge of the angle piece 262. v

The carriage return key, AT, is now depressed and the coupling members,26 and 30, are thereby engaged so that the two carriages, 4 and I99, aremoved together intotheir right-hand position in which, as alreadystated, the coupling members are disengaged by the left-hand marginsetter, RI, and the carriages 4 and I99, accordingly come to rest.Inasmuch as during the movement of the two carriages 4 and I99 to theright,

the roller 260 of the lever 251 has travelled on' the horizontaledge ofthe angle piece 262, no

line spacing movement was brought about; However, in order to writetheword "Adorf", the form has to be advanced to the next line. This maybe-easily acc mplished bypulling the knob 265b (Fig. 9) to he front,whereby the pawl 265 is disengaged from the line space wheel while onthe other hand, the platen I02 is rotated in the direction of the arrow268a until the next line is in writing position. -Thereupon thecarriages 4 and I99 are moved to the left by depressing the space bar Luntil the printing point for'the letter "A" (Fig. 10) ofthe 'word Adorfis in writing position, I

Now the address Adorf" is typed and the process which has just beendescribed is repeated. After a further return movement of the carriage,the'number "1560 and the name of the street are typed. As may be seenfrom Fig. 10, the number 45" of the street stands beyond the line 2.Consequently the carriages 4 and I99 have been moved so far to the leftof the line 2 in Figure 2b,, that the roller 260 of the lever 25 movesofl from the bevel 262a of the angle piece 262.

. The pawl 265 (Fig. 9) accordingly slides over the teeth 261 of theline space wheel 269. Now the carriage returnkey AT is again depressed.Dur

ing the movement of the two carriages to the right, the roller 260 ofthe lever 251 has travelled up on the bevel p of the angle piece 262 sothat the lever 251 is caused to swing in a clockwise direction.Consequently, the pawl 265 rotates the line space wheel 266 and with itthe platen I02 and the schedule in the direction of the arrow 268a. Asin the above operation, the schedule is not moved up to the level of theline, I, the pawl, 265, is disengaged from the line space wheel, 266,and then by operating the knob, 265b, with the assistance of the knob,I02a,-,Figure 2,

the platen, I02, is rotated in the direction of the arrow, 266a, untilthe line, I, is in the typing position.

The teeth, 23% to 2360, are now brought, by the operation of the lever,236k, into the position shown in Figure 5, in which they act upon thepart, 236, Figure 8, of the lever, 22?.

The two carriages 4 and I99 are again in their extreme right handposition according to Fig. 2, in which position the roller 260 assumesthe position according to line y, following to'which the printing pointon the platen I02 corresponds equally to the line 11 of the schedule,indicated in Fig. 10. From this, it may be seen that the roller 260 maynever be permitted to drop down at the right of the angle piece 262since the carriages come always to rest in the position according toFig. 2, owing to the fact that the coupling members 28 and 30 of thecarriage return mechanism are, as already mentioned above, disengaged bythe left-hand margin setter Ra: as soon as the carriages assume theirposition according to Fig. 2. Inasmuch as now the line I (Fig. 10) is inwriting position and the carriages 4 and I99 assume their positionaccording to Fig. 2, the amount 3900.00 may be registered.

By means of the calculating keys, R, the income amounting to RM 3900.00is registered in the column totalizer, 61, Figure '7, but it is notregistered in the two cross totalizers, I08 and I09, as the adjustingplates, I68a and I69a, of the column totalizer, 61, are adjusted to thedisengaged position. The following ,mechanisms are operated in the aboveoperation.

After the carriages, 4 and I99, have been moved into the thousandsdecimal position of the line numbered I, of the schedule, by means ofthe tabulator key, T I000, whereby the column totalizer, 67, also movesinto the operative 'position which corresponds to the thousandsposition, the calculating key, R, which corresponds to the figure 3 isdepressed. The corresponding key lever, 42, Figure 3, is thus swung in aclockwise direction around the shaft, 43, whereby the arm, 49, of thislever is disengaged from the nose, 58, of the pawl, 50, and consequentlythe pawl, is released. Under the action of the spring, 52, the pawl, 50,is now moved in the direction of the arrow, d, and with its nose, 53,engages with the ratchet wheel, 40, which rotates continuously. When thekey lever, 42, is depressed, the hook, 56, of the member, 54, is moved,

' under the action of the spring, 55, under the stop bar, 48, and thekey lever, 42, is thus held in its depressed position. As the cam, 5i,participates in the rotational movement of the driving shaft, 39, thecorresponding differential member, 60, moves in a downward direction.

The slot, 6I, formed on the differential member, 60, and shaped tocorrespond to the value of the key which has been depressed, acts uponthe shaft, 62, of the oscillatory frame, 64-65, 62- 64, which isrotatably mounted on the shaft, 63, whereby the shaft, 63, rotatesthrough an angle corresponding to the value of the key which has beendepressed, and registers the corresponding amount by means of theone-way toothed segment, 66, and through known mechanism, in the columntotalizer, 61, in an additive sense.

During the downward movement of the differential member, 60, the anglemember, 92, attached to it, acts upon the corresponding type key lever,95, which, by means of the pawl, 98, brings the coupling hook, 99, intoengagement with the toothed shaft, N, the resulting movement of thecoupling hook through the Inter- 229a, Figure 2, of the rack, 230, thecarriage,

"I99, will move as well as the carriage, 4.

The operation which has just been described. will be repeated at eachstep until the amount fRM 3900.00 has been registered in the columntotalizer, 61;

In consequence of the fact that In typing the last zero in the Pfennigeposition, the carriage has moved by one step, the part, 236, Figure 8,of the lever, 221, has run up on the tooth, 236?), Figure 2, of therack, 239a, and caused the tooth, 228, of the lever, 221, to disengagefrom the tooth, 22911, of the rack, 230, so that the carriage,

' I99, under the tension of the spring which is arranged in the casing,2", may move to the right, relatively to the lower carriage, 4. But asthe spring, 23I, which'is attached to the lever, 221, Figure 8, actsupon this lever, as soon as the tooth, 228, has been disengaged from thetooth', 22911, of the rack, 230, the carriage, I99, can move to theright only until the tooth, 228, engages with the next following tooth,229b, of the rack, 230. During the movement to the right of the carriageI99, the line spacing mechanism has not been operated since theroller260 has not left the horizontal edge of the angle piece 262 during theprevious leftward movement of the carriages.

In order to bring the schedule level with the line designated by II, theplaten, I02, is rotated by means of the knob, I02a, until the line, II,is in the typing position.

The two cross totallzers, I08 and I09, which, during the movement of thecarriage to the left, have been carried along by the coupling members,I65, I63, have also moved back into their right-hand position during thetyping of the Pfennige units.

But, as the two setting plates, I 68a. and I69a, of the columntotalizer, 61, are adjusted to disengaged, the cross totalizers have notregistered any amount, i. e. they are at zero.

The tabulator key, TI000, is again depressed whereby, the two carriages,4 and I99, move together into the thousands position, i. e., theposition immediately and vertically below the 3 of the alreadyregistered amount 8900.00,

on the schedule, the typing line, II, is in the typing position, whilethe thousands position of the column totalizer, 68, is in the operativeposition.

After the amount 6000.00 has'been registered in the same way as theamount 3900.00,'the carriage, I99, springs to the right in relation tothe carriage, 4, in the manner above described, whereby the formercarriage is held fast by the engagement of the tooth, 228, of its lever,221, with the tooth, 2290, of the rack, 230, so that the columntotalizer, 69, is located with its highest place, in the operativeposition, while the edge, M, Figure 2, of the figure column of thelines, I and II, of the schedule, are opposite the right-hand side wallof the column totalizer, 69.

As now, it is necessary to enter the tax amount 48.00" in the positionon the schedule Indl a'ed by, III, the upper carriage, I 99, must againbe moved to the left, relatively to the carriage, 4, into the positionas shown in Figure 2b. During this movement, the tooth, 228, of thelever, 221, slides over the teeth, 22% and 22911., of the rack, 230, andengages behind the tooth, 229a.

As the tooth, 229a, now lies on the left of the tooth, 236b, (Fig. 2b),it is no longer possible during the further movement to the left, of thetwo carriages, 4 and I99, for the tooth, 2361;, to act upon the part,236, of the lever, 221, and the release of the lever, 221, is noweffected by the tooth, 2360. The carriage, I99, having now been moved tothe left, the tooth, 228, of the lever, 221, is now between the teeth,23617 and 2360, and the edge M2, Figure 2b, of the figure column on thelines, III to XVIII, Figure 10, is positioned opposite to the right-handside wall of the column totalizer, 69.

The platen, I02, Figure 9, must now be rotated in the direction oppositeto that of the arrow, 268a, as far as the line, III, by means of theknob, I02a, while the pawl, 265, is disengaged.

The cross totalizers, I08 and I09, which have also moved back into theirright-hand position, are still at zero,-as the setting plates, I681; andI69a, of the column totalizer, 68, are adjusted to disengaged. I

The setting plates, I 68a and I69a, of the column totalizer, 69, are,however, both adjusted to addition so that'the amount 48.00 which is tobe registered in the column totalizer,,69, will also be registered inthe cross totalizer/I08, as well as in the cross totalizer, I09, in anadditivesense.

The tabulator key, TIO, Figure 2, is now struck, whereby the carriage,I, and the carriage, I99, are moved into the "tens decimal position onthe line, III, of the schedule, and the column totalizer, 69, isdisposed with its tens in the operative position.

When the calculating key, R, which corresponds to the value 4 is struck,this amount is again registered in the column totalizer, 69, by means ofthe parts already mentioned, and is at the same time typed on theschedule. When the carriage 4, moves to the left, the engaging member,I6I, which is on the column totalizer, 69, has, of course, also carriedalong the hook, I65, Figure 1, whereby, by means of the link, I63, thetwo cross totalizers, I08 and I09, have also been carried along untilthe cross totalizer, I08, is positioned with its tens opposite to thedriving wheel, I84, and the tens? of the cross totalizer, I09, ispositioned opposite to the driving wheel, I93, Figure 7. As the settingplates, 168a and I69a, of the column totalizer, 69, are adjusted toaddition and therefore pass inoperatively over the levers, I12 and I13,the gear wheel's, I82 and I92, are in direct mesh with their'gear wheelswhich arenot shown in the drawings, whereby the cross totalizers, I08and I09, are operated in the positive sense and the amount 48.00" isregistered at the inspection apertures of the two cross totalizers andalso in the column totalizer, 69.

When the last is typed in the Pfennige units position, the crosstotalizers, I08 and I09, are disconnected from the column totalizer, 69,and are engaged with the column totalizer, 10. At

the same time, in consequence of the step madeby the carriageimmediately after the striking of the key of the last "0, and also inconsequence of the face 236m, of the part, 236, of the lever, 221,contacting with the tooth, 2360, of the rack 23611, the lever, 221, isacted upon in an anticlockwise direction, whereby the tooth, 228, of thelever, 221, is disengaged from the tooth, 229a, of the rack 280. Thetension of the draw-band, 2I6, causes the carriage, I99. to be pulled inthe direction of the arrow, a. During this movement, as the lever, 221,is acted on by the spring, 23I, Figure 8, in a clockwise direction, thecarriage I99 is retained by the tooth, 229b, of the rack, 230, and themark, M2, of the schedule, which is shown in Figure 2b, is positionedopposite to the right-hand side plate of the column totalizer, 10.

Inasmuch as the carriages 4 and I99 have travelled from the line 2 inFig. 2b to the left, the roller 260 of the lever 251 slid oif from thebevel 262a of the angle piece 262, and has now, during the rightwardmovement of the carriage I99, been acted upon by the bevel 262a of theangle piece, 262, whereby the lever, 251, is swung around the screw,256, in a clockwise direction and against the action or the spring, 214.As the pawl, 265, which is arranged on the lever, 251, so that it canpivot thereon, is held in engagement with the teeth, 261, of the linespace wheel, 268, by the spring, 269, and at the same time participatesin the swinging movement of the lever, 2.51, the line space wheel, 268,is rotated in the direction 01' the arrow, 268a, shown in Figure 9, andthe schedule is shifted to the line, IV. I

The carriage, l, and the carriage, I99, which again moves with it, arenow moved by' means of the tabulator key, TIO, into the tens" decimalposition on the line, IV, of the schedule.

As the amount which is free from tax, i. e., RM 10.00, which is to beinscribed on the line, IV, is to be deducted from the amount of thetax, 1. e., RM 48.00 which is registered in the cross totalizers, I08and I 09, both of the setting plates, I 6811 and I 69a, of the columntotalizer, 10 are adjusted to subtraction. f

The calculating keys, R, which correspond to the arnount 10.00" are nowstruck, and the with it, by means of the link, I63 and the hook,

I65, until the amount registered in the column totalizer, 10, has alsobeen registered in thecross totalizers, I 08 and I09. As the settingplates, I68a and I69a, of the column totalizer, 10, are adjusted tosubtraction, the settingq plate, I68a, acts upon the cranked lever,I13,and disengages it by moving it in an anti-clockwise directionagainst the action of the spring, I16, whereby the connecting rod, I88,which is pivoted to it, acts upon the lever, I89, in a clockwisedirection, so that the gear wheel, which is connected with it and is notshown in the drawings, is brought into.

mesh with the intermediate gear wheel, I94, and the latter through thegear wheels, I92 and- I93, operates the number wheels of the cross totalizer, I09, in a negative sense, and in the cross totalizer, I09,theamount of RM 38.00 becomes I,

visible. of the column totalizer, 10, moves the lever, I12, in aclockwise direction whereby the connecting rod, I19, which ispivotablyc'onnected to it, acts At the same time, the setting plate, I69a, 3

upon the lever, I8I, in an anti-clockwise direction. This movement ofthe lever, I8I, causes the gear wheel, which is not shown in thedrawlugs, to mesh with the indermediate gear wheel, I81, and this causesthe number wheels of the cross totalizer, I08, through the gear wheels,I85

and I84, to rotate in a negative sense and in the inspection aperture inthe cross totalizer I00, v

the amount RM 38.00 appears too.

As soon as the carriages, 4 and I99, have moved to the position in whichthe last number position is out of the operative position, the crosstotalizers, I08 and I09, spring back to the right and the carriage, I99,is likewise released, so that it moves under the tension of thedraw-band, 2 I8, to the right until, the tooth, 228, of the lever, 221,engages with the tooth, 229e, of the rack, 230, under the action of thespring, 23I, whereby the edge of the schedule, M2, Figure 2, is nowpositioned opposite to the right-hand side wall of the column totalizer,II-

As the roller, 260,.ot the lever, 251, Figures 20 and 9, runs on to thesurface, 262b, of the angle piece, 262, the schedule is caused to moveupwards to the line indicated by, V.

Ihe amount which is registered in the cross totalizers, I08 and I09, isnow to be withdrawn from the cross totalizer, I08, and is to remain inthe cross totalizer, I09, while at the same time, it is to be registeredin the column totalizer, II, and typed on the line, V.

For this purpose, the tabulator key, TI 0, Figure 2, is again struck,whereby the carriage, 4, and the carriage, I99, move into the tensdecimal position on the line, V, of the schedule, and the columntotalizer, II, moves into the working position with its tens" place. Asthe amount 38.00" is to be withdrawn from the cross totalizer, I08, thesetting plate, I89a, of the column totalizer, II, is adjusted tosubtraction and as the amount of RM 38.00" is to remain in the crosstotallzer, I09,, the setting plate, 5811, is adjusted to disengaged.

By striking the corresponding calculating keys, the amount which is inthe cross total'izer, I08, 38.00, is registered in the column totalizer,II, and is also typed on the schedule, whereby the cross totalizer, I08,is returned to zero, and the cross totalizer, I09, is not operated atall.

The step movement of the carriage which is caused by the typing from thelowest denominational position of the cross totalizer, I08, causes alsothe projection, I2I, Figures 1 and 4, of the column totalizer, II, toact upon the hook, I20, of the lever, H8, and moves the latter to theleft, so that the lever, I20, releases the lever, I, whereupon, by meansof the parts, I39 and I43, the rake-shaped feeler rail, I45, acts inconjunction with the driving wheels, I09, of the number wheels, B. Ifnow the shortened teeth of the driving wheels, I09, are opposite to thefeeler guide rail, I48, in which case the amount 38.00 has been typedcorrectly, then the feeler rail, I411, may swing in a clockwisedirection under the action of a spring, which is attached to it but isnot shown in the drawings. The sliding member, I99, is thus caused tomove downwards and to swing, by means of the roller, I9I, the U-shapedrail, I99, the lever, I90 and the lever, I39, in a clockwise directionaround the shaft, I32. This movement causes the lever, I94, to act uponthe lever arm, I5I, of the lever I50, I52, I55, Figure and to swing italso in a clockwise direction so that the curved slot of the lever, I55,acts upon the lever, I59, Figure 1, whereupon, in a known manner, thetype lever which carries the clear sign type, impresses the clear signindication (a star) on the schedule after the amount The parts of theclear sign impression device which have thus been released foroperation, are

in a known manner, returned to their positions of rest by the action ofthe pin arranged on the intermediate lever of the clear sign type leveron the link, I58. As the intermediate lever on its forward movement, isswung in a clockwise direction, it moves at the end of its, forwardmovement, by means of its pin, the link, I58, in a direction opposite tothat of the arrow, :6, whereby the lever, I55, the two-armed lever, I52,I50, I5I, and the parts, I34, I33 and I30, are swung in ananti-clockwise direction and therefore, the lever, I24, can move withits notch over the lever, I30, under the action of its spring, I28.

At the same time, the cross totalizers, I08 and I09, are disconnectedfrom the column totalizer, II, and spring back into their right-handposition in readiness to be carried along by the column totalizer, I2,in the subsequent movement of the carriage, 4, to the left.

Furthermore, as the typing operation at the units position causes thecarriages to move by one step, and in consequence of the surface, 238m,of the part, 236, of the lever, 221, running up on the tooth, 2360, ofthe rack, 2360, the carriage, I99, is moved to the right and isdisengaged from the tooth, 2290, of the rack, 230, and in this movementto the right, retained by the tooth, 2290, of the rack, 230.

In this movement to the right, the roller, 260, of the lever, 251, isacted upon by the bevel, 2620., of the angle piece, 262, and the line,VI, of the schedule is raised into the typing position. The edge, M2, ofthe schedule, Figure 2, is thus positioned opposite to the right-handside wall of the column totalizer, I2.

The tabulator key, TI, Figure 2, is now depressed, whereby the carriage,4, and the carriage, I99, move into the lowest denominational decimalplace on the line, VI, of the schedule.

The calculating keys which correspond to the amount of RM 9.00 are nowactuated whereby in the column totalizer, I2, the amount 9.00 appearsand, as the setting plate, IBM, for the cross totalizer, 7 I09, isadjusted to addition, the is added to the amount amount of RM 9.00, RM38.00, which is already in the cross totalizer, I09, and the amount ofRM 47.00 appears in the inspection aperture. As on the other hand thesetting plate, I89a, for the cross totalizer, I08, is adjusted todisengaged this amount is not registered in the latter totalizer.

After the amount RM 9.00 has been registered, the carriage again movesby one step, whereby the cross totalizers, I08 and I09, are detachedfrom the column totalizer, I2, and are engaged by the column totalizer,I3. Furthermore, the lever, 22'I, is released from the tooth, 229d, andis engaged by the tooth, 229e, of the rack, 230. The schedule is alsomoved on to the line, VII, by means of the roller, 260, angle piece,282, lever, 2517, pawl, 285 and line space wheel, 208. Now the totalState taxes amount, which is in the cross totalizer, I09, is withdrawnfrom it and brought into the cross totalizer, I08. While the amount ofRM 47.00 is withdrawn from the cross totalizer, I09, this amount is atthe same time introduced into the column totalizer, I3.

In consequence of the carriage step movement which is caused by thetyping of the amount in be performed by the cross totalizers. The amount111.70 which is now in the cross totalizer, I09,

the lowest denominational positiomthe projection, I2I, of the columntotalizer, I3, acts upon the hook, II9, Figure 4, of the lever, III, andmoves it to the left so that the lever, I25, releases the-lever, I8I,whereby, by means of the parts, I35, I38, I40, I, the rake-like feelerrail, I48, acts in conjunction with the driving wheels, I49a, Figure 3,of the number wheels, Ba. It now the shortened teeth of the drivingwheels, 9a, are opposite to the feeler rail, Il8,-then this rail canswing in a clockwise direction under the action of its spring, which isnot shown in the drawings. In consequence of the swinging movement ofthe feeler 'rail, I48, the slide, I40, moves in a downward directionwhereby, by means of the already described parts, I5I, I52, and I55, theclear sign" is typed after the amount 47.00.

After the amount RM 47.00 has been entered in the column totalizer, I3,and into the cross totalizer, I08, and has been withdrawn from the crosstotalizer, I09, and the total tax amounting to RM 47.00 has been typedon the line, VII, the local rates amounting to RM 52.05 is typed on theline, VIII, and this amount is entered into both cross totalizers, I08and I09, so that in the cross totalizer, I08, the amount 1 RM47.00+52.05=99.05 is registered while only the amount 52.05 has beenregistered in the cross totalizer, I09. This amount of course, is at thesame time registered in the column totalizer, I4.

The fire brigade tax is typed on the line, IX, and added into both crosstotalizers, whereby the totalizer, I08,, shows the amount registered as-RM 99.05+7=106.05 and the cross totalizer, I09, shows the amountregistered as At the same time, the, column totalizer, I5, will show theamount 7.

The church tax is also added'in the two cross totalizers, I08 and I09,so that now the totalizer, I08, shows the amount registered as rates,which is registered in the cross totalizer,. I09, is now withdrawn fromit while the cross totalizer, I08, is adjusted to disengaged. In thisway, this amount is typed on the line, )H, and is registered in thecolumn totalizer, I1. If the amount 64.70 has been withdrawn correctlyout of the cross totalizer, I09, then in the manner above described, theclear sign will appear after this amount. Now the amount 111.70 which isin the cross totalizer, I08, is withdrawn, is typed on the line, XII, ofthe schedule and is at the same time registered in the cross totalizer,I09. If the amount has been withdrawn correctly out of the crosstotalizer, I08, the clear sign will appear after the amount 111.70.

At the same time this amount is registered in the column totalizer, I8..The other amounts which now follow and which are to be typed on theschedule are not registered in the column totalizers For this reason,the succeeding column totalizers, I9 to 9Ia, are blanks and serve onlyfor the control of the type of calculation to is typed on the line,XIII, after thelatter has been moved into position, whereby, the amountis withdrawn from the cross totalizer, I09, and introduced into thecross totalizer, I08. If the cross totalizer, I09, is at zero, the clearsign will again appear after the amount, 111.70. From this amount, 2%discount for the second to the fourth quarter is to be deducted, butwhile this is deducted from the amount which has been registered in thecross totalizer, I08, it is introduced into the cross totalizer, I09.The 2% discount=1.65 RM is typed on the line, XIV, of the schedule atthe same time asthe calculating operation is performed.

The amount which has been registered in the cross totalizer, I08, namelyRM 110.05" is now typed on the line, XV, of the schedule, whereby thecross totalizer, I08, is returned to zero and therefore the clear sign"appears, while the amount RM 110.05 is added to the amount 1.65 which isregistered in the cross totalizer, I09. The cross totalizer, I09,therefore, again shows the amount RM! 111.70.

After. the schedule has moved so that the line, -XVI, is in the typingposition, the amount, 111.70 is witrdrawn from the cross totalizer. I09,and is at the same time introduced into the cross totalizer, I08, and td on the schedule. When the amount is withdrawn from the crosstotalizer, I09, the clear sign again appears. After the schedule hasbeen moved so that the line, XVII, is in the typing position, the 2%discount is deducted fromthe amount of 111.70 which is registered in thecross totalizer, I08, whereupon, in this totalizer, the amount appears,while in the cross totalizer, I09, the amount RM 1.65 appears. Thelatter is also typed on the schedule on the line, XVII. Now the amountof RM 110.05 which can be seen in the cross totalizer, I08, is typedon.the line, XVIII, whereby the cross totalizer, I08, returns to zero,the clear sign star appears and the amount RM 111.70, appears in theinspection aperture of the cross totalizer, I09.

As this is the last amount to be entered in the vertical column, and theremaining amounts are to be entered into the column for receipts, theschedule must, in the first placefbe moved so that the line, XIX, is inthe typing position, and this is effected by disengaging the pawl, 205,by means of the knob, 285b, and rotating the platen, I02, Figure 9', bymeans of the knob, I02a', Figure 2, so far in the opposite direction tothat of I the arrow, 268a,.Figure 9, that the line, XIX, is in thetyping position.

The schedule is now positioned with the column containing the typelines, III to XVIII, opposite to the typing position, i. e. the mark,M2, Figure 2, is now opposite to the right-hand side wall of the blankcolumntotalizer, 85-, and the tooth, 228, of the lever, 221, is inengagement with the tooth, 22911, of the rack, 290. In order to so vbring the schedule into the column of the typing I lines, XIX to XXII,the upper, carriage, I99, is moved in relation to the lower carriage, 4,so far 'to the left that the mark, M3, is positioned opposite to theright-hand side wall of the blank totalizer, 85, whereby the tooth, 228,which until then, as already stated, had' engaged with the tooth, 22911,is now positioned again behind the tooth, 2291). Consequently, theroller 260 of the lever 25! is displaced further tothe left of line Z(Figures 2, 2a and 2b), namely, through that distance which corespondsto the distance from In this position of the two carriages, 4 and I99, I

the tooth, 229p, lies between the teeth, 2360 and 236d, of the rack,236a, that is, at each further step to the left of the two carriages,the tooth, 228, of the lever, 221, will no longer be disengaged by meansof the tooth, 2360, but by the tooth, 236d, from the teeth of the rack,230.

The tabulator key, TIO, is again depressed, whereby the two carriagesmove to the tens" decimal place on the line, XIX, and of the crosstotalizers.

The amount RM 29.20, is then subtracted from the amount RM 111.70 whichis in the v cross totalizer, I09, so that the totalizer now shows theamount RM 82.50, while the amount RM 29.20 is registered in the crosstotalizer, I08.

When the amount "RM 27.50 is typed on the lines, XX to XXII, the same isadded each time in the cross totalizer, I08, and subtracted in the crosstotalizer, I09, so that after the last amount has been typed, the crosstotalizer, I09, is at zero and the cross totalizer, I08, will show theamount RM 111.70.

After the amount typed on the line, XXII, the "clear sign will now beimpressed. The mark, M3, is positioned again opposite tothe righthandside wall of the blank column totalizer, 99, because the tooth, 228, isagain disengaged, and

in this position the end, I02b, of the knob, I020 typed on the slipswhich are on the right-hand.

edge of the schedule. For this purpose, the upper carriage, 4, is movedto the left until the mark, M4, is positioned opposite to the righthandside wall of the blank column totalizer, 89, whereby the tooth, 228, isdisposed behind the tooth, 229m, of .the rack, 230.

Accordingly, also the roller 260 of the lever 251 is displaced stillfurther to the left as above indicated, that is, its distance from theline 2 (Figures 2, 2a. and 2b) corresponds now to the distance from markM2 to mark M4.

In this position, the part, 236, which is arranged on the lever,'221,has slid over the tooth, 23611, of the rack, 236a, and is now one widthof-the totalizer to the right of the tooth, 236e,

of the rack, 236a, so that when the two carriages move further to theleft, the tooth, 236e, will release the lever, 22 1. The platen, I02, isnow rotated backwards by means of the knob, I02a, in the directionopposite to that of the arrow, 268a, until the line,

XXIII, is in the typing position.

By depressing the tabulator key, TIO, the carline, XXV, and finally theamount 27.50- onthe line, XXVI, of the schedule? these separate amountsare deducted from the amount registered in the cross totalizer, I08,while the cross totalizer, I09, is adjusted to "disengaged. When thelast amount 27.50 is withdrawn from the cross totalizer, I08, the "clearsign will appear after the last amount.

The above arrangement therefore provides 9.

constant control for the correct transfer of the amounts. Although nocontrol sign is printed, in connection with the amounts on the lines,XIX to XXI, and XXIII to XXV, no mistake can occur as the typist canonly type on the lines; XXII and XXVI, that amount which is in the crosstotalizer, so that the clear sign which is typed after the lastquarterly amount is also a control for the correct total amount of thefour quarterly instalments.

The carriage step movement which is released by the typing of the last"clear sign acts upon the margin setter, R1, which is arranged close tothe right-hand column totalizer, 9Ia, and causes it to actuate themechanism, not shown in the drawings, connected with the carriage returncoupling members, 28 and 30. The latter are thus engaged and thecarriages, 4 and I99, move to the right. In this movement, the carriage,I99, moves in stages to the right, relatively to the carriage, 4, untilthe part, 236, which is arranged "on the lever, 21, has passed all theteeth, 230a to 23Gb. When this has taken place, the carriage, I99, comesto rest with its righthand side against the stop, 28I, Figure 5, and thecarriage, 4, moves to the right alone, whereby the part, 236, slidesover the teeth of the rack, 230. When the carriage, 4, arrives at itsextreme right-hand position, the left-hand margin setter, Rm, acts againon the mechanism for operating the carriage return coupling members, 28and 30,

I and disengages these members, thereby bringing the carriage, 4, torest. The two carriages, 4 and I99, are then in their normal position asshown in Figure 2.

The rack, 230, which is exchangeable, may also be a smooth rack similarto a tabulator stop rail on which the teeth which release the lever,221, can be arranged like tabulator stops in such a manner that they canbe adjusted in position, and by this means the adjustment of thearrangement to any form of schedule is possible.

It is also not necessary that the teeth, 23Gb to 236e, should be of onepiecex'with. the rack, 236a. They can, instead, be arranged-on the part;2360., as adjustable stops. It remains to be added that the machine maybe changed atany time within a few minutes into a normally All that isrequired to be done, is to unscrew the connecting pieces, 242, 244,Figure 3, and 254,

Figure 9, of the upper carriage, I99, whereafter the latter can belifted off. After this the platen frame which corresponds to the lengthof the carriage frame, 4, is inserted in the frame, 4, and then themachine can be used in the manner already known.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is:--

1. In a typewriting and calculating machine, the combination of a maincarriage, means for moving said main carriage, an auxiliary carriagemounted in said main carriage, means for moving said auxiliary carriagerelatively to said main carriage, means for retaining said carriages inpositioned relation, together with'ineans operated by the movement ofboth said carriages for releasing said retaining means.
